Abstract: Le profil de facteurs de croissance, les constituants de la matrice de tissu conjonctif et le statut immunoprivilégié de la matrice extracellulaire (MEC) et du tissu conjonctif associé d'urodèle, ajoutés à la présence de peptides antimicrobiens, font du tissu dérivé d'urodèle une source idéale d'échafaudages biologiques pour la xénotransplantation. En particulier, un matériel biologique d'échafaudage biologique peut être obtenu par un procédé qui implique (A) l'obtention d'un échantillon de tissu sur un urodèle, le tissu comprenant la MEC, y compris la membrane basale, et (B) la soumission de l'échantillon de tissu à un processus de décellularisation qui maintient l'intégrité structurale et fonctionnelle de la matrice extracellulaire, grâce à la rétention de ses protéines fibreuses et non fibreuses, de ses glycoaminoglycanes (GAG) et de ses protéoglycanes, tout en retirant suffisamment de composants cellulaires de l'échantillon pour réduire ou éliminer son antigénicité et son immunogénicité à des fins de xénogreffe. Le matériel biologique dérivé d'urodèle obtenu peut être utilisé pour améliorer la restauration de l'homéostase de la peau, pour réduire la gravité, la durée et les dommages associés provoqués par une inflammation post-chirurgicale et pour activer le déroulement des processus de guérison et de régénération naturels.
